Aluminum alloy seat post clamp very similar to the old Tuf Neck clamps.
These were manufactured in 2013 from original 1980's tooling.
Color: BRIGHT DIP BLUE ANODIZED (sort of turquoise-ish blue)
Size: 28.6mm (1 1/8 inch) which fits many current BMX steel or chromoly frames that use a 1" (25.4mm) seatpost.
This is NOT an old school size (very few 1980's bikes used this size).
Brand new, in perfect condition, never used or mounted.
These were purchased in bulk so there is no retail packaging.
